Stego 15 MIL Vapor Barrier | 14' x 140'

Designed for contractors installing moisture protection under concrete slabs in residential and commercial construction, this vapor barrier provides reliable defense against ground moisture migration. The 15 mil polyethylene construction delivers puncture resistance during installation when working around aggregate base and rebar. At 14 feet wide by 140 feet long, each roll covers 1,960 square feet, reducing seams and installation time on large pours. Stego Industries manufactures this barrier to meet ASTM E1745 Class A standards for water vapor transmission. The material installs directly over prepared subgrade before concrete placement, creating a continuous moisture barrier that protects finished floors from vapor-related damage. Built for concrete contractors, builders, and foundation specialists working on projects requiring engineered moisture control systems beneath slab-on-grade construction.
